A Grid-based Framework for Pervasive Cross-Media Retrieval

Cross-media retrieval is an emerging and interesting research problem, which aims to breakthrough the restriction of modality during retrieval process. One basic challenge for cross-media retrieval is the efficient management and pervasive computing of multimedia content in heterogeneous, dynamic and distributed environment. In this paper, grid technology is introduced for its strongpoint in wide area information sharing and cooperation. Multimedia content is organized in a semantically coherent space. Efficient organization, indexing, and location of dispersed large multimedia content are discussed. Regarding the problem that multi-discipline digital libraries are isolated and dispersed without sufficient interconnection, a grid-based system framework and simulation platform are designed for case study
